Abstract
A method of decoding is presented. The method includes the steps of receiving a coded bit stream that is generated by encoding source information using a Non Return to Zero Inverted (NRZI) code, selecting an NRZI decoding method based on one or more parameters associated with noise in the received coded bit stream, and generating a plurality of decisions by processing the received coded bit stream using the selected NRZI decoding method, wherein the received coded bit stream comprises a plurality of coded bits, and the plurality of decisions are estimates of a plurality of source bits in the source information.
Claims23
A method, comprising:
- receiving a coded bit stream that is generated by encoding source information using a Non Return to Zero Inverted (NRZI) code;
- selecting an NRZI decoding method based on one or more parameters associated with noise in the received coded bit stream;
- and
- generating a plurality of decisions by processing the received coded bit stream using the selected NRZI decoding method,
- wherein the received coded bit stream comprises a plurality of coded bits, and the plurality of decisions are estimates of a plurality of source bits in the source information.
A system, comprising:
- a data storage device for storing a coded bit stream encoded using a Non Return to Zero Inverted (NRZI) code;
- a processing system communicatively coupled with the data storage device, wherein the processing system is configured to:
- select an NRZI decoding method based on one or more parameters associated with noise in the coded bit stream;
- and
- generate a plurality of decisions by processing the coded bit stream using the selected NRZI decoding method,
- wherein the coded bit stream comprises a plurality of coded bits, and the plurality of decisions are estimates of a plurality of source bits in a source information.
A communication system comprising:
- an encoder generating a coded bit stream that is encoded using a Non Return to Zero Inverted (NRZI) code;
- a decoder that receives the coded bit stream via a communication channel, wherein the decoder is configured to:
- select an NRZI decoding method based on one or more parameters associated with noise in the received coded bit stream;
- and
- generate a plurality of decisions using the selected NRZI decoding method,
- wherein the coded bit stream comprises a plurality of coded bits, and the plurality of decisions are estimates of source bits in a source information.
